Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to audiovisual equipment that uses a control bus line to easily control each equipment in a group of audiovisual equipment with a single remote control. It is something.

BACKGROUND OF THE INVENTION In recent years, with the advent of the AV era, it has become more common to enjoy audio equipment and video equipment at the same time. Moreover, on the other hand, HA (Ho
With the advent of the Automation era, we are entering an era in which these devices can be connected with control bus lines and complex control of these devices can be performed more easily and more reliably.

A conventional example will be explained below with reference to FIGS. 3 and 4, including a 3° color cathode ray tube (hereinafter referred to as CRT) 1, two left and right speakers 2.3, and a video disc player (
(hereinafter referred to as VD) 4, a commander (hereinafter referred to as COM) 5, its light receiving section 61, and a central remote control (infrared)
8 and amplifier (hereinafter referred to as human MP) 6, compact
This device includes a disk player (hereinafter referred to as CiD) 7 and a control bus line 25. Furthermore, this! fill The interface unit (hereinafter referred to as IFU) that allows the bus line 25 to enter each device.This IFU not only functions as a buffer between the external bus line and the device, but also decodes the command code and sends it to the device's microcontroller. 11.42°52.62.72 exists in each device. Furthermore, CRTl, VD4, AM
P6, CD717) respectively have 15, 45, 65
．． 75 for 00M5 and other FM devices, each a
It has a block that transmits a list of device names and function names such as play that can be controlled by the control bus line for each device. Additionally, C0M5 has a commander memory block 66. Further, the speaker 2.3 is connected to the output of the AMP6. However, the wiring is omitted in the figure. Similarly 'l/D4.

AMP6. CD7. The signal lines between the CRT1 are also omitted for simplicity.

On the other hand, the central remote control 8 is the above-mentioned device CRT1.

VD4, person MP6. It is equipped with a control key 81 that allows you to perform the necessary controls on CD7.

However, the name of the function that it controls is not written on that key. Instead, the control function name is displayed on-screen in the corresponding section on the CRTI, and you control it by pressing the corresponding key.

The operation will be explained below.

First, when you want to play the VD4, use the remote control 6.
When the power switch 8o is turned on, the characters vn, an, etc. are written in the section on the CRTl's on-screen. This is a centralized remote control 8
Commander 6's power by Nuwitch 8o
Each time the device is turned on, each device name is notified to the COM (commander) 5 from each jiM device via the control bus line 26 in response to a request from the COM (commander) 5, as shown in FIG.
Each consists of a symbol for displaying the name of the device on-screen and a code for calling the device. These are the results sent from the 4th N: which is the memory of each device. It is stored in the device name list memory of the commander memory block 66 of C0M6. Therefore, when you press the key corresponding to VD on the central remote control 8, the on-screen of the CRTl changes and VD is pressed.
The function names of D are PLAY, 5KIP, 5TOP...
They are arranged in sections like this. At the same time as pressing the key corresponding to VD on the central remote control 8, the contents of the function memory 45 from C0M5 to VD4 are transmitted back to C0M6 through the control bus line.・Each device consists of two parts: the on-screen display symbol of its own function name and the code when calling the function (these are sent from the 4th N: which is the memory of each device). ) Delete the old function name memory from the function name list of the commander memory block 56 of C0M6,
The new function name is written and this is the result that is immediately displayed on-screen. Therefore, the commander memory block 66 of C0M5 only has a memory containing a list of function names for the device in question.

FIG. 4A shows the name of the device being displayed on-screen. In the example, the on-screen appearance of the VD function name is shown. This means that the memory contents of the commander memory block (same as memory block 66 in 00M5) in Figure C are on-screen on the CRT1. By pressing the remote control key corresponding to PLAY, the VD4 will be played as desired.

On the other hand, to play "/Dff nibble" in the configuration shown in Figure 3, first, 1. Turn on the power of AMP6 to play the sound (settings such as volume are already set in advance) 2. , the play operation of the VD4 itself, etc., but in this case, due to the function of the control bus line 25, simply pressing the play compatible button on the VD central remote control 8 is necessary. , the above two main operations are transmitted to each +7Q 'A+'i by the control bus line, and each device operates according to the instructions via each IFU.In this way, the intended purpose is achieved. It means that it was done.

On the other hand, at the entrance of Figure 4, there are PLAY and 5KIP.

5TOP...9 functions can be on-screen, but I have already mentioned that the memory of vDl in the function name list in Figure C is on-screen. The VD2 on-screen in the function name list can be accessed by pressing the page key 82 on the remote control 8.
In addition to the nine functions of the D1, nine new functions of the D2 can be displayed and operated on-screen.

Hereinafter, regarding the play of the CD end, in the same way, when the key corresponding to CD on the central remote controller 8 on the screen of FIG. The old Senno name memory was erased from the function name list of C0M5's commander memory block 56, and the current CD
The new feature name is '+! F1 is loaded, and nine memories of CD1 corresponding to vDl in the function name list shown in Figure C are on-screen. Next, simply C of central remote control 8.
Just like in the VD station, you can accomplish your goal just by pressing the play button on the RTl's on-screen compatible CD.

Problems to be Solved by the Invention However, in the above configuration, when the explanation is given in FIG.
I explained that the number of functions in the device is 9, and the number of on-screen screens in the figure is also 9, but this is because the device C0M has 9 functions.
5 and VD4 are made by the same manufacturer and released at the same time, a convenient situation like this would occur, but in general, the above two devices are made by different manufacturers, or even if they are the same manufacturer, the release dates are different. However, the number of functions on the VDl and the number of on-screen functions in the same figure do not necessarily match.

At this time, the following problem occurs. That is, among the many functions, there are some functions that may be desired to be displayed as a pair on the same screen. For example, the VDl of the device memory block of a certain manufacturer's device video disk VD is 10.
Suppose that it is composed of ke. At this time, 81 in the 9th place of this VDl! :ARCH+function, 5 ICARC in 1Q
Assuming that the H-function is placed, this can be compared to the conventional C
If it is on-screened at 0M5, only nine functions are on-screened on a CRT, so S EA RCH+ is on-screened in the last column of the first page. And the first on-screen on page 2 is IKA.
1. RCH- will be on-screened. This creates an inconvenience in that the on-screens of two functions that are closely connected in this way will be on-screened on separate pages.

The present invention is intended to provide a solution to the above problems.

Means for Solving the Problems The audio-visual equipment of the present invention has a control bus line that connects each equipment to each equipment in the audio-visual equipment group.
A memory is provided to store a list of H names and function names.
The commander, which has the remote control receiver of the central remote control and is the central point of control for the audiovisual equipment group, decodes the signal from the remote control receiver and sends it as a command to the base 1i11+ bus line. List of device names from the above memory of the device?
The commander has the function of receiving the information through the control vane line, storing it in the device name list of the commander memory block of the commander, and writing the device name string in an orderly manner in the on-screen section on the CRT. l:, l, 7, n
1) The same section corresponding to the section on the cRT described above is set up as a key group on the centralized remote control, and the selection of machine number; ÷ is made by this, and the selected machine immediately The list is sent from the function memory to the list of function names in the commander's commander memory block, and the commander immediately divides it into several pages and displays it on-screen. Regarding the JiT function, an agreement has been made between the device and the commander so that it will not be on-screen for two pages, making it easier for the operator to control the device) (j9

Effect According to this (-1°11 composition), when the function name is on-screen, if a function 11 that should be a pair that cannot be separated comes, the commander will By exchanging them, there is a pair display (you can display the Ryono group on the same screen).

EXAMPLE An example of the present invention will be described below with reference to the drawings. FIG. 1 and FIG. 2 show an embodiment of the present invention.
It is a 1/i composition. Components having the same functions as those in FIGS. 3 and 4 showing the conventional example will be described using the same reference numerals.

A CRT, two left and right speakers 2, 3, a video disc player (hereinafter referred to as VD) 4, a commander (hereinafter referred to as COM) 5, its light receiving section 61, a central remote control (infrared) 8, and an amplifier controller, AMP 6. Compact disc player (hereinafter referred to as C)

hmm) .

It is equipped with a control key 81 that allows you to control. However, that key does not have the [geometrical name] jF for controlling it. Instead, the control function names are displayed on-screen in the corresponding sections on the CRT 1, and the control functions are controlled by pressing the corresponding keys.

The operation will be explained below.

First, when you want to play VDJ, use the remote control 6.
When the power switch 8o is turned on, the words VD, CD, etc. are written in the sections on the CRTl's on-screen. This is the name of each device that is notified in advance to the C0M5 from each device via the control bus line 26 in response to a request from the COM (commander) 6 each time the commander 5 is powered on by the power switch 80 of the central remote control 8. As shown in the 2nd N;, each device consists of a symbol for displaying the name of the punching device on-screen and a code for calling the device. These are the results sent from the machine name column in Figure 2 (e), which is the memory of each device. It is stored in the device name list memory of the commander memory block 56 of C0M5. Therefore, the VD of central remote control 8
When you press the key corresponding to , the CRT's on-screen will change, and the VD (7) function name will be PLAY and 5KIP.

They are arranged in sections like 5 TOP... At the same time as pressing the key corresponding to 'l/D on the central remote control 8, the contents of the function memory 46 of VD4 are transmitted from C0M6 to GOMS via the control bus line, and the same as in the case of the device name. As shown in the second drawing, each device consists of three symbols: the on-screen display symbol of its own function name, the function call 11.5 degree code, and the pair display symbol. This is the result sent from the memory in Figure 2 (E). The two points that differ from the above conventional example are that the above pair display symbol is added, and VDll and 21 are increased by 10 digits (good performance).C0M5. The old function name memory is erased from the function name list of the commander memory block 56, the new function name is written, and this is the result that is immediately displayed on-screen.Therefore, the commander memory block 56 of C0M5 The only memory that exists is a list of function names for the device in question.

FIG. 2A shows the device name niJ displayed on-screen. In the example, the on-screen appearance of the VD function name is shown. This means that the memory contents of the commander memory block 1+d2 (same as memory block 56 in 00M5) are on-screen on the CRT1. At this time, it should be noted that the number of VDlls in Figure 2 (e) is 10 as already mentioned.
, and the number of vDl in the second drawing is 9;
There are 5EARCH+ and 5EARCH- functions in the 10th position, and 5IRCH+ in the 9th and 10th positions.

5EARCH- is attached with the pair display symbol P1. This 'i56's commander memory block is like the vDl of the second drawing, and is the 8th KS EARC of the USSR.
H+, 9th KSEARcHf, H history, PAUSE is placed in the 1st position of VD2. If you press the remote control key corresponding to PLAY at the mouth of Figure 2, the VD4 will play as desired.
The game is played in the same way as in the conventional example.

On the other hand, to play a VD, with the configuration shown in Figure 1, you first need to: 1. Turn on the power to the AMP6 in order to copy the sound (settings such as volume are already set in advance) 2. , the play operation of the VD4 itself, etc., but in this case, due to the function of the control bus line 26, simply pressing the play compatible button on the VD central remote control 8 is necessary. , the above two main operations are transmitted to each device by the control bus line and transmitted through each IFU,
Each device operates according to its instructions. In this way, the intended purpose has been achieved.

On the other hand, at the entrance of Figure 2, there are PLAY and 5KIP.

5TOP...9 functions can be on-screen, but I have already mentioned that the memory of vrJl in the list of function names of the same figure is on-screen, but the function in the same figure The name list of VD2 on-screen can be accessed by pressing the page key 82 on the remote control 8.
In addition to the nine functions of the VDl, nine functions of the new '/D2 can be displayed and operated on-screen. This is the same as the conventional example.

Effects of the Invention As described above, according to the present invention, related functions are displayed on the same screen, which is convenient for the operator.
